Pear And Orange Jam With Walnuts - cooking recipe

Ingredients

4 1/2 cups prepared fruit (about 2 1/2 lb. fully ripe pears and 2 medium or 3 small oranges)
1/2 cup chopped walnuts
5 1/2 cups sugar
1 box sure-jell fruit pectin (powdered)
1/2 teaspoon butter

Preparation

Peel and core about 2 1/2 pouds pears.
Peel oranges, remove seeds and any loose membrane. (I used \"juice\" oranges, not navels, for a more intense flavor.).
Grind or chop pears and oranges very fine.
Mix well.
Measure 4 1/2 cups of the mixture into a very large saucepan.
Add 1/2 cup chopped walnuts.
Measure sugar and set aside.
Mix pectin into fruits in saucepan.
Place over high heat, stirring continually, until the mixture comes to a hard boil.
Immediately add all the sugar and butter and stir well.
Bring to a full rolling boil and boil hard 1 minute, stirring constantly.
Remove from heat and skim off any foam with a metal spoon.
Stir and skim for 5 minutes to cool slightly and prevent floating fruit.
Ladle quickly into glass jars, wipe rims and apply lids & rings.
Process in a water-bath canner for 10 minutes for half-pints, 15 minutes for pints.
Remove from canner and place jars on a clean towel to cool.
